Her popularity has seen Milly sign a book contract and she regularly speaks out about mental health awareness.

Examples of Milly's pictures

A recent photo added to Milly's Instagram feed showed her in lingerie eating a slice of pizza, while putting a middle finger up to the camera.

The caption said: "Just dropping in to let you know that 95 per cent of diets fail. Diets have been clinically proven TO NOT WORK yet we blame ourselves when we fail rather than the money grabbing, life ruining culture.

"Healthy eating doesn't have to be a damn diet! It's odd that we as a society we think they are exclusively linked.

"Diet culture does NOT give two hoots about your health. It's about size, conformity and obedience/self hatred. Your body will do what it wants to damn well do however it needs to do it, you can NOT manipulate that.

"Live your damn life, listen to your body, it's not the enemy, it freaking loves you. Instead of embarking on another expensive shit fest of a diet for the 20th time in your life take a different route of intuitive living."

'You're perfect as you are'

Milly often tries to encourage young girls to keep their self-belief up, highlighted best in another picture that shows a photo of her breasts, complete with stretch marks, in which she says she "wishes she'd seen images like this when I was 13."

In the post, Milly challenges what most young girls see now, as Instagram, social media and magazines have taken over the role of what others have seen in times gone by, an often unachievable look that has been enhanced with technology and airbrushing.

"I didn't think it was normal, I thought I'd be seen as hideous. I saw these gravity defying, smooth skinned, insanely plump breasts plastered over every magazine. I wish I'd seen images of real breasts, models wearing a padded bra under their bra, airbrushed marks and scars, photoshopped plumpness. I wish I saw breast like this when trying on bras and shopping for underwear.

"So for anyone out there struggling to love their breast stretch marks then here's that image. You're normal, beautiful and perfect as you are."

'Your body is not offensive'

In another post, Milly challenges the stereotypes around women with body hair and slams society for making women think having leg, armpit, body and pubic hair should be ashamed.

"Make this the first summer you finally wear shorts. Make this the first summer you finally allow your tattas to roam free.

"Make this the first summer you don't give a f***. Make this the first summer that you embrace every inch of you."

'Milly - you're an inspiration'

Many of Milly's 176,000 followers praised her for her honest post and said she was an inspiration.

One said: "You are such an inspiration and damn girl you ARE RIGHT! This is the year I don;t wear antiperspirant because it contains toxic aluminium! This is the year I'm not afraid to wear low cut tops and let my boobs show! It's hot dammit!"

Another said: "Every time I see your posts I instantly feel better about the way I look without makeup because you make me realise that I shouldn't give a s*** as long as I'm happy and comfortable."

Even the boys got involved in praising Milly for her brave post. He said: "I'd have to admit as a young boy growing up being told this is wrong my gut reaction is still the same, but my gosh you look amazing!"

Just last week, the body-positivity activist told her excited followers that she had signed a book deal.

She said the book will be based around mental health, mindfulness, "adulting" and self-care and acceptance. She told her followers "watch this space" and said she had "dreamt of this day since being a little girl."

We can't wait to see what she gets up to next.
